Abstract

We report new measurements of the parity-violating asymmetry APV in elastic scattering of 3 GeV electrons off hydrogen and He4 targets with θlab ≈ 6.0°. The He4 result is APV=(+6.40Â±0.23(stat) Â±0.12(syst))Ã-10-6. The hydrogen result is APV=(-1.58Â±0.12(stat)Â±0.04(syst))Ã-10-6. These results significantly improve constraints on the electric and magnetic strange form factors GEs and GMs. We extract GEs=0.002Â±0. 014Â±0.007 at Q2
